1984191 divided by 348 
The aim is to understand the frequency of 348 in 1984191.

Moving on to step 1:
When dividing 1 by 348, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 348

On to step 2:
348 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 348

Advancing to step 3:
The number 348 fits into 198 0 times, leaving a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 198 after subtracting 0 from 198.
Bring next digit (4) of the dividend behind the 198 and repeat the process: 1984 / 348

Let's proceed to step 4:
When dividing 1984 by 348, we get 5 with a remainder of 244.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 1740 away from 1984, we end up with 244.
Bring next digit (1) of the dividend behind the 244 and repeat the process: 2441 / 348

On to step 5:
When dividing 2441 by 348, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we subtract 2436 from 2441, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 348

Step 6:
59 divided by 348 is 0 with a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 570.0
The remainder is 59 after subtracting 0 from 59.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 348

On to step 7:
348 can be fit into 591 1 times, resulting in a remainder of 243.
Put 1 as the next digit of the answer. 
Result so far: 5701.0
Deduct 348 from 591 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 8:
348 can be fit into 2430 6 times, resulting in a remainder of 342.
Put 6 as the next digit of the answer. 
Result so far: 5701.6
The remainder is 342 after subtracting 2088 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 9:
3420 divided by 348 is 9 with a remainder of 288.
Put 9 as the next digit of the answer. 
Result so far: 5701.69
Deduct 3132 from 3420 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 10:
348 can be fit into 2880 8 times, resulting in a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 5701.698
If we subtract 2784 from 2880, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
960 divided by 348 is 2 with a remainder of 264.
The number 2 becomes the next digit in our result. 
Result so far: 5701.6982
If we subtract 696 from 960, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 12:
348 can be fit into 2640 7 times, resulting in a remainder of 204.
Use 7 as the next digit of our solution. 
Result so far: 5701.69827
If we take 2436 away from 2640, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 13:
If we divide 2040 by 348, we get 5 and a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 5701.698275
Subtract 1740 from 2040 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 14:
348 goes into 3000 8 times with a remainder of 216.
Put 8 as the next digit of the answer. 
Result so far: 5701.6982758
Subtracting 2784 from 3000 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 15:
348 goes into 2160 6 times with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 5701.69827586
If we subtract 2088 from 2160, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 5701.69827586, with a leftover of 7.2e-08.
